Numerical Analysis on Diffusion Mechanism of Prefabricated Technology Under Government Intervention Based on Evolutionary Game

Abstract

The diffusion of prefabricated construction technology is an important guarantee for industrialization of construction industry. To investigate the roles of government, developers and contractors in the diffusion of prefabricated construction technology, a three-way evolutionary game model of prefabricated construction technology diffusion is introduced, and the influence of external factors related to game players on the diffusion of prefabricated construction technology is analyzed based on the evolutionary game model. With the numerical simulations conducted by system dynamics software of Vensim, the evolutionary trends under different initial conditions are dynamically displayed, and the results demonstrate that reducing the cost of diffusion assembly construction technology, is conducive to improving the enthusiasm of developers and contractors to share the prefabricated construction technology. Besides, appropriately increasing government incentives is conducive to promote the diffusion of prefabricated construction technology
